After recently purchasing this from my fellow basschatter I used the V4B at rehearsals.
My concerns about how loud were soon dismissed, these heads for 100W are loud.
Its an excellent match to the SVT212AV cab and has a great Ampeg growl / grind tone.
The EQ is very easy to work with and I found it was better not using my compression pedal instead go straight in with my bass.
Last night I used my Ray34 and the band said it was by far the best sound they had heard from me.
Naturally I’m super pleased about this and I suspect this will be my small to medium venue rig and use my ABM600 rig for larger or outside gigs.
I ran the master fully open last night on the V4B and used the gain control for volume, sounded great.
Tried it today and I think I prefer the master as required and use the gain set around 3pm
Also found today I like the Ultra Low ON ( it only boosts the bass a bit and reduces 500hz) but I turn the bass control down a little and crank the 800hz control. This seems to be a sweet spot for the amp, will see how it sounds next week when played louder with the band.
Anyone who likes a great rock sound for small to medium sized gigs I can recommend this amp and cab.
Better than my ABM600 ( nope ) just different in feel and tone.
